Problems solved by technology

Even though some water-saving irrigation technology measures have been adopted in some places, they have not fully played a good role in forestry due to limitations such as weak specialization, high cost, and complex engineering.
[0006] (2) Poor afforestation effect, low survival rate and preservation rate
[0007] Due to the lack of necessary and advanced watering technical measures for afforestation and greening in arid areas, once encountering insufficient water and untimely watering, it will affect the normal growth and survival of seedlings, and even seriously reduce the survival rate and preservation rate of seedlings
When there is severe water shortage, the seedlings will die and greening will fail
Not only caused a certain economic loss, but also affected the effectiveness of afforestation
[0008] (3) High waste of resources, especially water resources
The previous water use method not only wastes a lot of water resources, but also creates water conflicts with other industries, and the effect of watering cannot be effective and sustainable

Embodiment 1

[0034] as attached Figure 1-2 As shown, the annular drip irrigation container in this embodiment includes a water storage bag 1 , a water injection port 2 arranged at the upper end of the water storage bag 1 , and a flow-adjustable dripper 4 arranged at the lower end of the water storage bag 1 . Both ends of the water storage bag 1 are provided with fixing belts 7 for fixing the water storage bag 1 , and the fixing belts 7 are provided with fixing holes 3 for passing the fixing rods 5 . A sealing ring 6 is provided at the connection between the water storage bag 1 and the flow-adjustable dripper 4 .

[0035] When using the method of this embodiment, the water storage bag 1 is placed around the base of the tree so that the fixing straps 7 at both ends are overlapped, and the fixing holes 3 on the two fixing straps 7 are overlapped, and the sharp end of the fixing rod 5 is passed through After the fixing holes 3 of the two fixing bands 7, they are fixed in the soil to prevent ...

Embodiment 2

[0038] as attached Figure 3-5 As shown, the annular drip irrigation container in this embodiment includes an arc-shaped water storage tank 8, a water injection port 2 arranged at the upper end of the arc-shaped water storage tank 8, and three flow-adjustable type dripper4. The arc-shaped water storage tank 8 is composed of a tank body 9 and a tank cover 10. The water injection port 2 is arranged on the tank cover 10. The bottom of the tank body 9 is tapered, which is conducive to drip irrigation of water downward and reduces the storage of water.

[0039] When using the method of this embodiment, the curved water storage tank 8 is surrounded by the seedlings through the gap of the curved water storage tank 8, the external water source is connected through the water injection port 2, the curved water storage tank 8 is filled, and the arc is twisted. The flow-adjustable dripper 4 at the lower end of the arc-shaped water storage tank 8 is turned on, and the water in the arc-sha...

Abstract

The invention relates to an adjustable-flow independent drip irrigation method for plantlets, which includes: laying a circular drip irrigation container around each plantlet; using an external water source to fully fill each independent circular drip irrigation container through a water injection hole on the circular drip irrigation container; and adjusting adjustable flow droppers at the bottom of each circular drip irrigation container to perform drip irrigation for the plantlets. The adjustable-flow independent drip irrigation method for plantlets is mainly intended for the need of plantlet watering and is highly targeted. The flow is adjustable in drip irrigation, so that water is saved. The method is simple and convenient in operation, skills are easy to master, transplant survival rate and storage percentage of the plantlets can be increased, and water and labor cost can be saved.

Description

technical field [0001] The invention relates to an independent drip irrigation method for seedlings with adjustable flow rate. Background technique [0002] The current micro-irrigation technology focuses on the large-scale operation of agriculture and animal husbandry, and a certain area of ​​pipeline system is often laid. The laying of micro-irrigation projects is usually continuous, large-area, and fixed. The micro-irrigation system also requires connection to a fixed water source. , especially suitable for large-scale crop production, such as irrigation of wheat, lawns, vegetables, flowers, nurseries, etc., and there is no micro-irrigation device and technology specifically for seedling planting management. [0003] The current nursery stock irrigation technology used in forestry has the following outstanding problems: [0004] (1) Extensive management, low technical content, labor-intensive and time-consuming management [0005] In most cases, after the seedlings are...
